August 3, 20232 yr Heya! Been checking a lot, asking a friend who uses unRAID etcetera. Am not entirely clear yet: I got a 4TB parity drive. Functioning well. I bought an 8TB drive to replace the parity drive and move the current 4TB parity drive to a data drive slot. I am a bit lost on what order is best. I think: 0: Do a parity check. 1: I should stop the array. 2: Unassign the current parity drive. ...guessing now: 3: start the array (not sure why) 4: Stop it again. 5: Power down. 6: Place the new 8TB drive in place of the current 4TB parity drive 7: pre-clear that one 8: stop the array 9: It says to unassign the parity drive (which one? the emulated one?) 10: Assign the 8TB as the parity drive 11: and then I am lost Truly been looking. Should be an easy step, either I did not search well enough or there is no clear guide step by step ? *shrug* ...after 11...and some steps perhaps, follow a guide or just add the old parity drive to the system (stop/power down) etc...and assign it as a data drive... Please let me know if I am wrong with the first 10 steps and which few steps needs to be done after 10 then .... I did read Parity Swap ... Thanks very much! /z Edited August 3, 20232 yr by zwientie grammar
August 4, 20232 yr Author Solution I'm overthinking it right ? Would explain me not finding guides :).
August 4, 20232 yr Author I'll add the 8TB, pre-clear it for sanity 😛. Stop array. Unassign 4TB parity. Start array - get an emulated parity. Stop array. Assign 8TB as parity. Let it build the parity on that. After all is done do the steps to make the old parity drive a data drive. Besides, as the manual says, it will remain a backup parity in the mean while. Correct ? 😛
August 4, 20232 yr Community Expert Just now, zwientie said: Start array - get an emulated parity. All correct except that at this point there will be no parity (I.e. it is not emulated).

You mean, there IS an emulated one but it is not a real parity, just to keep it all running ? I did not know either btw, that unRAID can run without parity drives. (Why not, just did not know ...:).) Thanks y'all ! 😛 There's I dunno...a lot of data, don't wanna lose it ...obviously :).

August 4, 20232 yr 8 hours ago, zwientie said: a lot of data, don't wanna lose it Unraid or any RAID isn't backup, it's high availability, where a failed drive can be emulated and replaced while your data is still accessible. Backup implies the ability to recover from a corrupted or deleted file, which requires a second copy somewhere besides the array. You need to have a second copy away from the array of any data you can't afford to lose.
